Activitybegilbert-sys commented on Jul 12, 2021 MannequinAuthor More actions I use turtle pretty often in a teaching setting. It's extremely common that I'll define the following function at the top of my code:
def teleport(x, y):
turtle.penup()
turtle.setpos(x, y)
turtle.pendown()Shouldn't this sort of method already exist within the turtle class? vedgar commented on Jul 12, 2021 In my view, turtle is a great tool for exploring _polar_ coordinates. If you set emphasis to rectangular coordinates, there are many tools that are much better.
Second, your function might be ok for you, but it is really not suitable for standard library. Probably you meant something like (a method)
def teleport(self, *args):
restore = self.isdown()
self.penup()
self.setpos(*args)
if restore: self.pendown()serhiy-storchaka commented on Jul 12, 2021 What other Turtle implementations support the teleport command? begilbert-sys commented on Jul 12, 2021 MannequinAuthor More actions Turtle is the most accessible and well-known drawing module for kids to use so teleporting makes more sense in the context of drawing random shapes or small pictures around the screen. I've seen the penup/goto/pendown combo so often that I figure it at least warrants a suggestion. Also my crappy function was mostly just meant as an outline, haha. liam-gersten commented on Apr 17, 2023 Hello, my name is Liam, and I’m part of a student software engineer group of 4 at Carnegie Mellon. We’ve been tasked with contributing to an open source project, and this issue seems like a great first start. Would you mind assigning this to me (my group)? Also, you might see the same comment on 1-2 other issues, since we’ll likely be working on more than just one for our assignment. gpshead commented on Apr 28, 2023 FWIW I agree that a teleport is a useful feature addition.
Some existing other Turtle teleport references:
teleport is mirroring the existing goto/setpos/setposition absolute cartesian positioning API, but with more convenient semantics. A polar coordinate system teleport would be a different api and is out of scope for this feature request.
i'm reviewing the PR. gpshead commented on Apr 30, 2023 Thanks for your contribution Liam, merged. We don't often touch the turtle module as it's a bit of a leftover thing that we keep in the standard library because of its usefulness in educational settings, but this feature addition made sense.
